UNITED STATES CLARK J. BROWN, OF PLYMOUTH, NEW HAMPSHIRE.

IMPROVEMENT m OILrCANS.

Specification forming part of Letters Patent No. 129,783, dated July 23,1872.

I, CLARK J. BROWN, of Plymouth, in the county of Grafton and State ofNew Hampshire, have invented a certain Improvement of a Self-CheckingOil-Gan Spout for filling metallic lamps, to obviate running themover,

of which the following is a specification:

My invention relates to the combination of a' small metallic tube andgage to a spout of an ordinary coal-oil can, in such a manner that saidtube will control the flow of oil out of the can when the oil reaches acertain height in the metalliclamp, as it is very diflicult to see whena metallic lamp is nearly full, or as full as it ought to be withoutrunning over.

i The accompanying drawing represents an oil-can, one side of the upperpart removed so as to show the attachment. I

A is the reservoir or can. It has only one opening, into which the spoutB is screwed. Can A is so put together as to form an airtight chamberwhen the end of spout B is closed. D is a small curved tube, fastenedonto the insideof spout B, extending through spout B into reservoir A.Tube D is bent in such a manner that the end will be above the fluid,and not to strike or interfere in unscrewing the spout B. 0 serves as 'agage, and is made of a piece of wire soldered to the under side of spoutB to regulate the height of oil in the lamp.

. In filling a lamp the spout B is placed into filler of lamp as far asgage 0 permits it; the can A raised sufficient to let the oil flow out.Tube D supplies the necessary air to the reservoir. As long as the oilhas not yet reached the end of spout B or end of tube D the oil willcontinue to flow; but the instant the oil raises to that height the tubeD will cease to furnish the necessary air, and the oil as shown.
